During the Christmas period, altcoins will experience a rebound, and the reason is simple: platforms like Binance and OKEx are closed during U.S. stock market hours, and investors cannot trade ETFs and MSTR. During this time, Bitcoin will not experience significant fluctuations, making it an ideal opportunity to speculate on altcoins for profit. Therefore, altcoins will surge before Christmas week and then drop significantly afterward, completing a short-term fluctuation. Be cautious of risks when chasing highs; it's a quick in-and-out strategy. Once U.S. stock investors return from their holidays, Bitcoin may experience significant volatility again.
